Phoenix Contact 1702044 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1702044 is a 5-position terminal block header from the COMBICON DFK-PC series, designed for front panel wire connection via male pins with PCB-mounted right-angle rear connections. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations. The part features threaded mating lock and shield connection feedthrough capabilities, with a standard 0.400" (10.16mm) pitch configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1702044 is determined by the following critical parameters:

• Series Compatibility: Both parts must belong to the COMBICON DFK-PC series to ensure mechanical and electrical interchangeability
• Connector Type: Front panel connection via male pins and rear PCB connection via right-angle pins
• Pitch Standard: 0.400" (10.16mm) pitch maintains consistent spacing and mating interface
• Voltage Rating: Minimum 600 V UL rating required
• Panel Mount Configuration: 2-piece snap lock front flange mounting system
• Physical Dimensions: Width of 3.392" (86.16mm) and panel thickness tolerance of 0.039 ~ 0.118" (1.0 ~ 3.0mm)
• Regulatory Compliance: RoHS compliant status

The substitute part 1701566 maintains all these core parameters while differing in position count (6 positions versus 5 positions) and current rating (66 A versus 5 A). These differences represent functional enhancements rather than incompatibilities, as the substitute accommodates additional connection points and higher current capacity within the same mechanical envelope and series specification.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1701566 serves as the active substitute for the obsolete 1702044 within the COMBICON DFK-PC series. Both components maintain identical mechanical mounting specifications, electrical voltage ratings, and series compatibility. The transition from the 1702044 to the 1701566 is supported by:

• Product Status: The 1701566 maintains active product status, ensuring continued availability and manufacturing support, whereas the 1702044 is obsolete
• Regulatory Compliance: Both parts are RoHS compliant, meeting current environmental and safety standards
• Series Continuity: Both components belong to the COMBICON DFK-PC series, guaranteeing mechanical and electrical interchangeability within the series specification
• Inventory Availability: The 1701566 is available in higher quantities (1038 pcs) compared to the 1702044 (978 pcs), supporting production continuity

Selection of the 1701566 as a replacement accommodates applications requiring either the original 5-position configuration or expanded 6-position connectivity, with the added benefit of significantly higher current capacity (66 A versus 5 A).

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1701566 directly replace the 1702044 in existing designs?

A: Yes. Both components share identical pitch (0.400"), panel mount configuration (2-piece snap lock), width (3.392"), voltage rating (600 V), and series specification (COMBICON DFK-PC). The 1701566 provides one additional position and higher current capacity within the same mechanical envelope.

Q: What is the primary difference between these two parts?

A: The 1702044 provides 5 connection positions with a 5 A current rating, while the 1701566 provides 6 connection positions with a 66 A current rating. Both maintain identical pitch, mounting system, and physical dimensions.

Q: Why is the 1702044 listed as obsolete?

A: The 1702044 has been discontinued by Phoenix Contact. The 1701566 represents the active product line continuation within the COMBICON DFK-PC series.

Q: Are there any compatibility concerns when substituting the 1701566 for the 1702044?

A: No compatibility concerns exist for mechanical mounting or electrical interface. The additional position on the 1701566 does not affect existing 5-position applications. PCB layout modifications may be required if the additional 6th position is not utilized.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the 1702044 and 1701566 are RoHS compliant and carry identical UL voltage ratings of 600 V.

Q: What panel thickness range is supported by these terminal blocks?

A: Both components support panel thickness from 0.039" to 0.118" (1.0 to 3.0mm), accommodating standard panel mounting applications.
